The condensation reaction involving an o-aminoaryl ketones with alpha-methylene ketones via the tandem addition/annulation reaction by the ionic liquid of [Hbim][BF4] (IL) as a solvent with methanol as co-solvent at room temperature under ultrasound irradiation afforded the corresponding quinolines derivatives in excellent yields. The use of ionic liquid(More)
Novel terpyridine-functionalized MCM-41 nanoporous silica was synthesized and characterized by X-ray powder diffraction (XRD), infrared (IR) spectroscopy, transmission electron microscopy (TEM), and thermal (TGA-DSC) and elemental analyses. The application of functionalized nanoporous silica was investigated for the removal of chromate, which is one of the(More)
Azo-hydrazone tautomeric behavior of polyazo Solophenyl red 3BL (C.I. Direct 80) dye in different solvents (water, methanol and DMSO) was investigated using 1H, 13C, NH, HH, CH COSY, HH NOESY NMR techniques and UV-vis spectroscopy. Two-dimensional NMR experiments were used to assign 1H, 13C and 15N NMR lines unambiguously. Results showed that the(More)
